U.S. Attorney Joe Hogsetts announced charges Wednesday against Christopher Rennard, 28, Westfield. Rennard, a volunteer wrestling coach at Westfield High School, faces charges including possession of child pornography, distribution of child pornography and shipping or transporting by means of computer visual depictions of minors engaged in sexually explicit conduct.

A report from Dropbox—a cloud file sharing service—alerted investigators to the case via a tip to the Cyber Tip Line by the National Center for Missing and Exploited Children. According to the Dropbox report, someone had uploaded and stored files containing child pornography between Jan. 15 and Jan. 27, 2014. Investigators traced the account and IP address to Rennard.

On April 17, special agents from Homeland Security Investigations and task force officers from the Hamilton County Metropolitan Child Exploitation Task Force served a search warrant at Rennard’s residence. According to the affidavit, Rennard was home at the time and admitted to collecting and distributing child pornography.

Investigators said Rennard contacted other child pornographers using an iPhone app called Omegle. They would exchange links, images and videos stored in Dropbox accounts so they could be downloaded and copied.

Prosecutors said Rennard could face up to 20 years in prison and a $250,000 fine.

The case came as part of Project Safe Childhood and Hogsett’s “Operation Community Watch.”
